SPECIFICATION forming Letters Ifatent No. 760,645,.dated May 24,1904.

' 'Application filed March 18, 1904.

To all whom, 11157771601] concern." 7 7 Be it known thatI, ROBERT P. PnAnsoNya citizen of the United States, and a resident of Gloucester City, county of Camden, State of New Jersey, have invented an Improvement in Loom-Temples, of which the following description,'in connection with the accompanying drawings, is a specification, like numerals on the drawings representing like partsl This invention has for its object the production of a loom-temple provided with novel means for effecting the return or inward move- .ment of the temple-head after the same has been moved outward by or through engagement with the lay of a loom. p

In the usual form of temple,"wherein the shank is slidably movable in the fixed stand, a spiral spring is employed toeflect the' return movement of the head, the spring being alternately compressed and expanded and"fre quently being exposed, rendering it liable-to In my present invention I have provided a rotatable springactuated controller mounted on the stand and in positive engagement with and. to move the head inward, the spring being concealedand protected from injury, and as it is in the 'nature of a clock-spring it /will bear longer and operate in a more uniform manner than the ordinary spiral wire spring. g

Figure 1 is a top or plan view of a loom temple embodying my invention. Fig.2 is a side elevation of the stand, a portion of the Fig. 3 is a longitudinal sectional detail on the line 3 3, Fig. 1; and Fig. 4: is a right-hand end view of the controller detached. r

The temple-head 1, Fig. 1, having in practice the usual toothed roll (not shown) and having an attached heel 2, may be of usual or well-known construction, said head having a rigidly-attached and elongated shank 3 slidably mounted in the stand 4, the latter having a slot 5 to receive the clamping-bolt by which it is attached to the breast-beam of a loom, as usual. A longitudinal guide-slot 6 is made in the outer end of the shank to receive a stud 7 fixed in the stand and provided with ahead Serial No. 198,712." (No model.

8, overhanging the sides of the slot to guide the shank in its longitudinal movement and alsoto prevent it from tipping on the stand. Two parallel upturned ears 9 are formed on the stand at its innerend, between which the shank slides, "and on a stud.10,held,in the cars, is mounted a rotatable spring-actuated controller, shown as a cylinderor'drum 11 having segmental teeth 12 on a portion. of its periphery to engage the teeth of a rack 13,

herein shown as forming a part of the shank 3 and on the upper face thereof. .A clockspringlt (see Fig. 3) is coiled inside of the drum, and one end of the'spring is secured to the d'rum,'as at 15. The other end of the spring is attached to a pin 16, extended from one tothe other of the ears 9 and fixedly held.

therein. I

In order to permit rotative movement of the controller or drum, the ends thereof are provided with slots, 17, Fig. 3, concentric with the axis 10, the pin 16 passing through said slots. When the lay beats up and engages the heel 2, the head and its shank are moved outward in the direction of arrow18, Fig. 3, and the rack-and-pinion connection between the shank and controller 11 causes the latter to be rotated in the direction of arrow' 19, winding up or setting the spring of the controller. As the 'lay moves back the spring 14 unwinds and rotatesthe controller in the opposite direction to arrow 19 and the segment-gear 12 acts through the rack 13 to move the shank and head inward into the position shown in the drawings. Inward or return movement of the shank is limited by the stud 7, as will be manifest, and the stopshoulder 20 at'the end of the gear 12 also engages the top of the shank at the outer end of the rack, as shown in Fig. 3, to form an additional stop.

The breadth of the shank and controller permit the employment of longfteeth in the rackand-pinion connection, steadying the mover'nentof the parts and preventing rapid wear of the teeth. x

In order to introduce the spring into the drum, one end thereof is made removable, such the end piece 21 to prevent rotation thereof relative to the drum. The spring is inserted in the drum and fixed thereto at 15, after which the end piece 21 is put into position and the drum placed between the ears, after which the fulcrum-stud 10 is positioned. Then the pin 16 is passed through one ear 9 and through the hooked end of the spring and into the other car, said pin passing through the drum ends by means of the slots 17.

Changes or modifications may be made in various details of construction without departing from the spirit and scope of my invention hereinbefore set forth and illustrated in the accompanying drawings in one practical form, and particularly pointed out in'the following claims.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a loom-temple, a stand, a head having a shankslidably mounted in the stand, and a rotatable spring-actuated controller carried by said stand and cooperating with the shank to *move the head in one direction.

2. In a loom-temple, a stand, a head having a shank slidably mounted in the stand, and provided with rack-teeth, and a rotatable spring- 'controller to eifect return movement of the temple-head by spring-induced rotation of the controller.

3. In a loom-temple, a stand, ahead having a shank slidably mounted in the stand, and provided with rack-teeth, a rotatable drum carried by the stand and having peripheral teeth in mesh with the rack-teeth, and a spring coiled within the drum and attached thereto at one end, the other end of the spring being fixedly held, outward movement of the temple-head winding the spring, reverse and spring-induced rotation of the drum effecting return movement of the temple-head.

4. In a loom-temple, a stand, a head having a shank slidably mounted in the stand,a springaetuated controller rotatably mounted on the stand, and a rack-and-pinion connection between said controller and the shank.

5. In a loom-temple, a stand having npturned, parallel cars, a head having a shank slidable on the stand between the cars and provided with a rack, a drum rotatably mounted on the ears and having concentric openings in its sides, a segmental gear on the dru m in mesh with the rack, a spring within and attached at one end to the drum, and a holding-pin connected with the other end of the spring and fixedly secured in the ears, said pin passing through the openings in the sides of the drum.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
